Clyde R. Fickes BY L020 8 Barry Attorneys United States Patent O3,211,359 ROLL-ON BOOK WRAP Clyde R. Fickes, Des Moines, Iowa, assignorto Hoerner Boxes, Inc., Keokuk, Iowa, a corporation of Delaware FiledMar. 16, 1964, Ser. No. 351,986 7 Claims. (Cl. 229-40) This inventionrelates to a carton for wrapping books for shipping or mailing and moreparticularly to a book wrap having improved strength characteristics aswell as improved sealing and opening features.

There are many types of book wrap cartons presently on the market, mostof which fail to provide adequate protection for the ends and corners ofthe book. A number of specially designed book wraps are available whichutilize cellular inserts to protect the ends of the book and in someinstances air cells of special design. When a cellular insert is used,special assembling is required to mount the insert in the box. The aircell type cartons generally are designed to be .sealed by means ofspecial machinery. This involves a further expenditure in order to usethese book wraps.

One object of the present invention is to rovide a book wrap which canbe automatically sealed on standard equipment.

Another object of the present invention is to provide a book wrap whichprotects the article to be shipped from damage due to impact.

A further object of the present invention is to provide a book wrap thatcan be easily opened by the use of a tear strip.

Still another object of the present invention is to provide a book wrapthat can be readily adjusted to accommodate different thickness books.

A still further object of the resent invention is to provide a book wrapthat has a self-locking closing system.

These objects are accomplished by dividing a single blank ofcarton-forming material into inner, bottom and top panels separated byend walls hingedly connected to said panels. One of said end walls ishingedly connected by slit scores along a substantial length of thehinge so that the end wall can be used as a tear strip. The inner panelhas end wall sections hingedly connected to each end of the panel withan overlay section hingedly connected to said inner panel end walls.Wing flaps are hingedly connected to each end of the overlay sectionswhich act as spacers at each end of the box. End flaps n the top andbottom panels are folded into engagement with the projecting ends of thewing flaps so that an air space or cell is rovided between the flaps andthe end walls. This space acts to cushion any hard blows or bumps whichmay be encountered in shipping or mailing. The overlapped end fia-ps canbe sealed in a conventional sealer or selflocking tabs can be providedthrough the end flaps.

Other objects and advantages will become more readily apparent from thefollowing detailed description when read in connection with theaccompanying drawings, in which:

FIG. 1 is a diagrammatic view of a carton blank.

FIG. 2 is a view of the blank folded to the intermediate position, and

FIG. 3 is a view of the blank completely folded with a part of the teartype end wall turned back.

Referring more specifically to the drawings, the roll-on book wra ismade from a single blank of corrugated material having flutes runningtransverse to the longitudinal axis of the blank. The blank is dividedinto an inner panel 12, top panel 14 and bottom panel 16 separated by atear-type side wall 18 and side wall 19. Slit scores 20-22 are made inthe hinged connections of the tear-type side wall with a small hingedconnection 21, 23 left at the end of each of the slit score lines. Theend 3,211,359 Patented Oct. 12, 1965 can be torn from the blank bymerely pulling on tab 25. Score lines 2446 provide the hinged connectionbetween the other side wall and the inner and top panels. End flaps 28and 30 are hingedly connected to the bottom panel by score lines 32 and34 and end flaps 36 and 38 are hingedly connected to the top panel byscore lines 40 and 42.

End walls 44 and 46 are hingedly connected at one side to the innerpanel by score lines 48 and 50 and to overlap sections 52 and 54 byscore lines 56 and 58. Wing flaps 6 62, 64 and 66 are hingedly connectedto the ends of the interlocking sections by score lines 61, 63, and 67.The wing flaps are made longer than the width of the overlap sections byseparating the ends of the wing flaps from end flaps 44, 46 by slits 68,70, 72 and 74. Slits 68, 72 are extended inward a short distance toseparate raised sections 76 and '78 from the end flaps.

Two small tabs 80 are provided in each of the end Walls adjacent toscore lines 48 and 50. These tabs when turned inward, act as spacers tohold a book of less thickness than the width of the end walls fromrattling in the box. The tabs shown are designed to provide a book wrapfor two diiferent thickness book-s but it should be apparent that thetabs can be cut to accommodate any of a number of different thicknessbooks.

A book is wrapped in the carton by placing it on the inner panel 12. Endwalls 44 and 46 are folded upward along both of the ends of the book andoverlap sections 52 and 54 folded inward over the top of the book. Thewing flaps 62, 66 are folded downward into alignment with score line 22and wing flaps 60, 64 folded downward into alignment with score line 26.The wing flaps should abut the ends of the end walls 46 and 46. A smallportion of the wing flaps will project outward beyond side walls 44 and46 with wing flaps 6i) and 64 in side by side relation to side wall 19.End flaps 36 and 38 are then turned upward into engagement with theprojecting end of The wing flaps.

The folded inner and top panels are then folded over side wall 22 ontobottom panel 16 with the surface of inner panel 12 in surface contactwith the surface of the bottom panel. End flaps 28 and 30 are thenfolded upward against end flaps 36 and 38. An adhesive is normallyapplied to the overlapping surfaces of the end flaps to seal the carton.This adhesive may be applied by any of the conventional gluing machinessuch as the Seco Case sealer. The end flaps may also be stitched orselflocking tabs 86 (shown dotted) can be provided in each of the endflaps that merely have to be pushed in to interlock the end flaps. Theblank is cut and scored so that a close fit is provided along all seamsto protect the book from foreign matter. Raised sections '76 and 78close a gap that normally is present between the edge of bottom panel 16and the score line 26.

To open the carton, the tear-type side wall 18 is torn along the slitscore lines by pulling on tab 25. Once this side wall has beencompletely removed, wing flaps 62 and 66 can be turned on score lines 63and 67 to open the side of the carton completely.

Although only one embodiment of the present invention has been shown anddescribed, it should be apparent that various changes and modificationscan be made without departing from the scope of the appended claims.
